The all-welded plate heat exchanger has a corrugated plate structure similar to a plate heat exchanger, is sealed by adopting an all-welding process, is free of gasket design, and has the advantages of high heat transfer efficiency, small terminal temperature difference, high temperature and high pressure resistance, compactness, light weight and the like.
Disclosure of Invention
The utility model discloses a become full welded plate shell type soda heat exchanger of runner solves traditional heat exchanger because the steam inlet initial stage steam flow velocity is too fast, makes the board trade the high temperature section heat exchange rate and can not reach best effect, realizes promoting the effect of heat exchanger heat exchange rate.
For realizing above-mentioned technological effect, the application discloses a change runner all-welded lamella soda heat exchanger, which comprises a housin, the casing top is equipped with steam inlet, one side that bottom was equipped with the condensate outlet, top one side was equipped with water outlet and bottom is equipped with the water inlet, still is equipped with the heat exchange plate group of compriseing a plurality of heat transfer boards, forms an air flue between arbitrary two adjacent heat exchange boards, heat transfer board thickness is by steam inlet one side grow gradually to condensate outlet one side, makes an air flue width diminishes gradually to condensate outlet one side by steam inlet one side.
Furthermore, a partition plate is arranged inside the heat exchange plate to form a secondary water channel, and the secondary water channel is communicated with the water outlet and the water inlet.
Furthermore, the secondary water channel is in an inverted V shape from bottom to top.
Furthermore, the baffle plates are sequentially arranged on two sides in the heat exchange plate at intervals.
The beneficial effects of the utility model include:
(1) the utility model discloses a steam passage top-down diminishes gradually in full-welded plate heat exchanger, slows down the board and trades the initial section steam flow rate of steam inlet.
(2) The inner secondary water channel of the plate is gradually reduced from bottom to top, the inner secondary water flow of the plate is gradually accelerated from bottom to top, and the heat exchange rate of the high-temperature section of the plate is increased, so that the overall plate exchange efficiency is improved.
(3) The utility model discloses equipment structure is simple, and work efficiency is high, and the structure sets up rationally, and the cost is lower, is favorable to promoting and using.

The first embodiment is as follows:
the variable-flow-channel all-welded plate-shell type steam-water heat exchanger shown in fig. 1 and 2 comprises a shell 9, wherein a steam inlet 1 is formed in the top of the shell, a condensed water outlet 2 is formed in the bottom of the shell, a water outlet 3 is formed in one side of the top of the shell, a water inlet 4 is formed in one side of the bottom of the shell, a heat exchange plate group consisting of a plurality of heat exchange plates 5 is further arranged, a primary air channel 6 is formed between any two adjacent heat exchange plates, the thickness of each heat exchange plate is gradually increased from one side of the steam inlet to one side of the condensed water outlet, and the width of the primary air channel is gradually decreased from one side of the steam inlet to one side of the condensed water outlet.
A partition plate 7 is arranged inside the heat exchange plate to form a secondary water channel 8, and the secondary water channel is communicated with a water outlet and a water inlet. The secondary water channel is in an inverted V shape from bottom to top. The baffle sets up in the both sides in the heat transfer board at interval in proper order.
Steam enters the primary air passage 6 from the steam inlet 1, the primary air passage becomes smaller gradually from top to bottom and is arranged in a V shape, and after the steam enters, the flow rate of the steam at the initial section of the steam inlet 1 is reduced. Water flow enters from the water inlet 4, the secondary water channel 8 is in an inverted V shape from bottom to top, and after the water flow enters the heat exchanger, the flow rate of the water flow is gradually accelerated from bottom to top through the secondary water channel, so that the heat exchange rate of the high-temperature section of the plate is increased, and the overall plate exchange efficiency is improved.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; the invention is not limited to the embodiments described herein, but is capable of other embodiments with obvious modifications, variations, and equivalents without departing from the scope of the invention.
